JOHN H. RAWLINS, OF UPLAND, PENNSYLVANIA.

RESILIENT TIRE FOR VEHICLE-WHEELS.

Application filed January 21, 1909.

To all whom it may concern:

Be it known that I, JOHN H. RAWLINS, a citizen of the United States,residing at Upland, in the county of Delaware and State of Pennsylvania,have invented certain new and useful Improvements in Resilient Tires forVehicle-lVheels; and I do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

This invention relates to improvements in resilient tires for vehiclewheels.

The object of the invention is to provide a tire of this characterhaving arranged therein a series of springs and means for holding saidsprings in position whereby all the advantages of a pneumatic tire willbe obtained without the annoyance and danger which result from thepuncturing or bursting of pneumatic tires.

lVith this and other objects in view, the invention consists of certainnovel features of construction, combination and arrangement of parts aswill be more fully described and particularly pointed out. in theappended claims.

In the accompanying drawings, Figure 1 is a side View of the wheelshowing the application of the invention thereto; Fig. 2 is alongitudinal sectional View of a portion of the rim and tire of thewheel; Fig. 8 is a cross sectional view through the rim and tire; Fig. 4is a detail cross sectional view of the rim showing one of the springsof the outside row or series of springs and illustrating the manner inwhich these springs are tied at their upper ends to prevent lateralmovement of the tire; Fig. 5 is a similar view showing the manner oftying the springs in the outside row at the opposite side of the rim.

Referring more particularly to the draw ings, 1 denotes a wheel and 2denotes the rim which is preferably formed of wood and which may be ofany suitable shape and provided with suitable outer surface, saidsurface being shown in the present instance as being fiat. The rim isprovided adjacent to its outer surface with laterally project ingannular flanges 3, the purpose of which will be hereinafter described.

Arranged around the outer surface of the rim are series of coiledsprings 4, said springs being preferably arranged in par- Specificationof Letters Patent.

allel annular rows. Each of the springs is secured at its lower end tothe outer surface of the rim by suitable fastening devices 5. Each ofthe springs of the outer rows are secured or tied, at their upper ends,to the opposite side of the surface of the rim by brace or tie wires 6which are preferably an extension of the upper end of the spring andwhich form means for bracing the upper ends of the springs of the outerrows and for holding the tire against lateral movement. This manner oftying or bracing the outer rows of springs is clearly illustrated inFigs. 4 and 5 of the drawings.

Arranged around the outer ends of the springs is a retaining strip 7which is in the form of a fiat band constructed of leather, canvas orother suitable material having the required stiffness and strength tohold the springs in shape. The upper ends of the springs are held inproper position against the under side of the retaining strip 7 by meansof studs 8 which are secured to the under side of the strip or band 7 asshown.

Arranged over the springs and retaining strip 7 is a tire 9 which may beformed of any suitable water proof fabric having the required strength.The inner edges of the tire 9 are secured to the side of the rim belowthe flanges 3 by means of annular clamping rings 10, said rings beingbolted in position by transversely disposed bolts 12 which are insertedthrough the rim and through the rings 10, as shown.

on the tread surface of the tire is arranged a shoe 1?) which may be ofany suitable construct-ion and is here shown as being in the form of aseries of annular corrugations or ribs.

A tire constructed as herein shown and de scribed will be comparativelyinexpensive in construction, etlicicnt and reliable in operation andwell adapted for the purposes for which it is designed.

From the foregoing description, taken in connection with theaccompanying drawings, the construction and operation of the inventionwill be readily understood without requiring a more extendedexplanation.

Various changes in the form, proportion and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of the invention as defined in theappended claims.

Having thus described my invention, what I claim as new and desire tosecure by Letters-Patent is:

1. A resilient tire for vehicle wheels comprising a rim, a series ofcoiled springs arranged in parallel annular rows and secured at theirlower ends to the rim, tie or brace rods to connect the upper ends ofthe springs of the outer rows to the opposite sides of the rim wherebythe tire is held against lateral movement, a flexible retaining striparranged around said springs, a flexible tire adapted to cover andinclose said springs and strip, and means to secure the inner edges ofthe tire to the side of the rim.

2. A resilient tire "for vehicle wheels com prising a rim, a series ofcoiled springs secured at their lower ends to the rim the upper ends ofthe springs of the outer rows being extended to form braces, said bracesbeing secured at their free ends to the o aposite side of the surface ofthe rim and a exible tire secured to the rim and adapted to cover andinclose said springs.

A resilient tire for vehicle wheels comprising a rim having laterallyprojecting annular flanges, a series of springs arranged around said rimand secured thereto at their lower ends, a retaining strip arrangedaround said springs, holding studs arranged on the inner side of saidstrip to engage the upper ends of the springs whereby they are held inposition, a flexible tire arranged around and adapted to inclose saidsprings and strip, clamping rings adapted to secure the inner edges ofthe tire below the flanged edge of the rim, fastening bolts arrangedthrough said rim and clamping rings, and a corrugated shoe arrangedaround the tread surface of the tire.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses;

JOHN H. RAVVLINS.
